naca duct for helmet cooler
I want to install a koolbox helmet cooler, where is it legal to mount a naca duct on a spec boxster? I was told the rear lexan is a no no. Hope someone can point me to a solution.

I saw a rear lexan naca duct last weekend on a SPB. Also wondering what to do if I get a helmet blower. Let us know if you find out more.
What with recent discussions about whether intake scoops are allowed, I wonder if the same logic would imply that naca ducts are similarly allowed. I always thought that all this kind of stuff (changes to bodywork not specifically called out) was illegal.

Hello Trygve, it's Branimir. I hope your well and your cars all fixed up after FOS. I ask PCA about placing it in the rear window and was informed it would not comply with the rules.

that was my original idea, but pca rejected that idea due to aero along with the rear window option. I was hoping to hear what others have done and passed scrutineering. Thanks for your response

I run air to my Stilo. Not being able to get an answer about NACA duct, I routed the intake hose so it is grabbing fresh air from passenger "window"
It works well enough.

The rule book is actually pretty clear where intakes or NACA ducts are permitted.
